BATTER-MACHINE.

SPECIFICATION forming part of Letters Patent 110.629 60'7, dated July 25, 1899. A lication filed October 5, 1898. Serial No. 692 ,687. (N model.)

To all whom it may concern: 7

, Be it known that I, JOHN CALVIN ROBERTS, of Bedford, in the county of Bedford and State of Pennsylvania, have invented anew and Improved Batter-Machine, of which the following is a full, clear, and exact description.

This invention relates to improvements in machines for making or forming batter for cakes or the like; and the object is to provide a machine of this character in which the ingredients for forming the batter may be quickly and thoroughly reduced to the proper consistency and then stirred together and made ready for the oven.

I will describe a batter-machine embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a batter-machine embodying my invention. Fig. 2 is'a section on the line 2 2 of Fig. 1. Fig. 3 is a perspective view of a locking-pin employed. Fig. 4 is a vertical section with the fiour-sifter removed. Fig. 5 is a section at right angles to Fig. 4. Fig. 6 is a section on the line 6 6 of Fig. 5. Fig. 7 is a side elevation showingthe parts in position for operating the flour-sifter. Fig. 8 is a vertical section thereof, and Fig. 9 is a section substantially on the line 9 9 of Fig. 8.

The machine comprises, a main body portion 1, a crusher-casing 2, anda Sifter-casing 3.

Y The bottom of the body portion 1 is rounded,

as plainly indicated in the drawings, and is supported by legs 4. As a means for fastening the device to a tablel employ a hookshaped clamping-Wire 5, which has its body mounted to rotate in bearings 6, formed by the Wires of the legs 4. The hookvportion of this clamp is designed to engage underneath the top of a table, shelf, or the like.

The sugar-crusher casing is provided with a barrel portion 7 and a hopper 8. In the bar-. rel portion is mounted to rotate a conveyer and crusher comprising fan-blades 9, having a spiral trend on the shaft 10, and at the end of these blades is a spiral conveyer 11, which at its ends communicates with the spiral crusher 12, which has projections 13, designed to grind the sugar, to be pressed against adisk 14, 11w ing projections 15 on the side adjacent to the crusher portion 12, and this disk is provided with openings, which are formed between the projections. in the bottom of the barrel is an outlet 16 for sugar, this outletbeing substantially in line with the crushing devices, and is designed to allow the passage of sugar to the body portion 1 of the device, as will be hereinafter described.

Mounted in the body portion 1 is a beater consisting of yokes or arms 17, extended radially from hubs 18 18, through which a shaft 19 loosely passes. The inner end of the shaft 19 has an angular portion 20 to engage in a correspondingly-shaped openingiu the hub 18, and the said shaft has a reduced cylindrical portion 21, designed to engage in a cupbearing 22, formed on the body portion and having its outer end closed. This shaft 19 is movable longitudinally for purposes to be hereinafter described, and its outer end is provided with a pinion The end of the shaft 19 adjacent to the pinion 23 has a bearing in a lug 24, formed on the body portion of the casing, and removably mounted on this lug is a gearing-frame consisting of a vertical member 25 and laterally-extended members 26 27.

When in position on the machine, the gearing-frame has its lower end engaged by a clip 28 on the body portion, the arm or lateral extension 26 engages with a clip 29 on the body portion, the lateral extension 27 engages with a clip 30 on the body portion, and the upper end of the vertical member engages with a clip 31 on the body portion. The gearingframe is held from rotation by means of a pin 32, which engages with the upperside of the lateral extension 27 and passes into a keeper 33. The pin 32 is not only intended at a certain time to lock the gearing-frame in position, but it is also intended to make an operative connection between a driving-wheel 34 and the shaft 10 of the crusher, Therefore this pin is made angular in cross-section, and

one direction it maybe removed from the hub but by turning it in the opposite direction it will rotate the hub. This hub is provided with a longitudinal central opening corresponding to the shape of the pin 32, which is designed to pass through said opening and into the opening of the shaft 10. The hub is mounted to rotate in the upper portion of the gearing-frame. On its inner end the hub has an annular flange 37, which is countersunk into the inner side of the gearing-frame, as plainly indicated in Fig. 6. Therefore this flange will have its inner face flush with the inner face of the gearing-frame.

When the shaft 19 is moved inward to its operative position, with its pinion 23 engage ing with the gear 34, the said shaft is held in place by means of a spring-latch 38, which is pivoted on the lower end of the vertical member 25 of the gearing-frame. This latch 38 is designed to engage with its ends yieldingly against the center of the pinion 23. The latch has an opposite extension 39, provided with a valve 40, designed to close the opening through the lug 24 when the shaft 19 is removed, as will be hereinafter described.

A closure is also provided for the opening 41 in the casing when the crushing device is removed. This closure comprises a plate 42, extended laterally from the stem 43, mounted to move vertically in suitable guides 44 45. The closure 42 is moved automatically to its closing position by means of a spring .46, fastened at one end to the body portion of the machine and engaging at the other end with a pin or other device on the stem 43. The upper end of the casing 2 has a flange 47, designed to bear upon the upper end of the casing or body portion 1 when the crushing device is in position, and this flange 47 is also designed to engage with the upper end of the stem 43 to force the closure 42 downward when said casing 2 is inserted, so that the pin 33 may be inserted.

In the casing 3 is a sieve-bottom 48, and an agitator, comprising wire arms or yokes 49, is mounted on a shaft 50, arranged to rotate in the casing 3 and having on its outer end a gear-wheel 51, designed to be placed in engagement with the gear 34, as will be described in the operation. When the sifter is in use, the crushing device is to be removed from the casing or body portion 1 and the sifter put in its place, and to prevent the sifter from moving too far downward into the casing 1 I provide it with flanges 52, designed to engage upon the top of the casing 1.

Figs. 1 and 2 show the arrangement of the several parts when the device is not in actual use. This arrangement makes the device convenient for packing or storage.

In operation the flour-sifting device is to be removed with the crusher left in the easing 1. During the operation of crushing or grinding the sugar the heaters 17 are to remain stationary. Therefore the latch 38 is to be moved out of engagement with the pinion 23, so that the shaft 19 may be drawn outward to disengage the pinion from the gear 34, as plainly indicated in Fig. 5. The proper amount of sugar is now to be placed in the hopper 8, and the amount or number of pounds may be gaged by grad uating-marks 53, formed on the interior of the hopper. As before stated, by placing the casing 2 in position the plate 42 will be moved downward, so that the pin 32 may be passed through the hub 36 and into the shaft 10. Now by rotating the gear 34 by means of its crank 54 the crusher Will be rotated, the blades 9 will move the sugar into engagement with the con veyer-blade 11, and this will convey the sugar to a point between the crushers l2 and 14, where it will be thoroughly pulverized, and this pulverized sugar will fall through the opening 16 into the body portion of thecasing 1. After placing the pulverized sugar in the body portion or casing l the pin 32 is to be removed and placed in the keeper 33, and then the crusher is to be lifted out. After this the shaft 19 is to be moved inward, so that the pinion 23 meshes with the gear 34 and is locked in place. Then by rotating said gear 34 the heaters 17 will be operated to thoroughly mix the sugar with the eggs that have been previously placed in the body portion or casing 1. The sifter is now to be placed in position. When in position, its gear-wheel 51 will mesh with the main gear 34, so that by rotating the main gear 34 the arms 49 in the sifter will be rotated, as will also the beaters in the body portion; but the beaters in the body portion will be rotated much faster than the arms in the sitter, because the pinion 23 is much smaller than the gearwheel 51. This will cause a complete and rapid mixing of the several ingredients to form the batter. \Vhen the batter is 001m pleted, the sifter is to be removed. Then the shaft 19 is to be drawn completely out, so that the heaters 17 may be removed. Then the plug or valve 40 is tobe turned to close the opening of the lug 24. After this the formed batter may be poured out into suitable molds or baking-pans ready for the oven.

The gearing-frame is made removable, so

that it may be thoroughly cleaned or washed and also that the outer side of the casing may be washed.

The beaters 17 may be of any preferred and suitable form, and instead of a series of beaters a single beater may be employed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
